Catch one of the After Dark: Sexplorations highlights from February 6, 2014! Watch as Exploratorium Biologists, Karli Woodward and Caitlin Johnson demonstrate a live sea urchin fertilization. Watch highlights from our live webcasts with the E/V Nautilus as she explored the Mediterranean and Black Seas searching for shipwreck, deep sea vents and the communities of organisms that live in these extreme environments. There are green sea turtles in San Diego Bay? Where did they come from? Do they really live over 100 years? Why is it important for scientists to keep track of these giant creatures, and how on earth do they do it? In this interview with ecologist Tomoharu Eguchi (NOAA Marine Fisheries Service) and ecology graduate student Sheila Madrak, we meet the sea turtles and explore these 'big' questions. Join the Exploratorium for our final webcast with researchers on board the Nautilus. We discuss the highlights of their three month expedition to the Mediterranean and Black Seas, as well as to the eastern Atlantic Ocean. Learn about hydrothermal vents, organisms living in extreme environments and ancient shipwrecks. The Nautilus has discovered several well-preserved shipwrecks on their mission, from ancient Greek trading vessels to modern sailboats. Join us as we talk with chief scientist Katy Croff Bell live aboard the Nautilus and see the latest video of their discoveries. Located in the Atlantic Ocean off the coast of Portugal, the seamounts of Gorringe Bank rise nearly 5000 meters from the sea floor -- as tall as Europe's Alps. Join us as we talk live with scientists aboard the Nautilus as they explore these geologically active and biologically rich submarine mountains. Join the Exploratorium as we connect live for the first time with the E/V Nautilus as it sails the Mediterranean Sea south of Spain. We talk with scientists on the ship and learn about the ship's amazing capabilities and the 2011 exploration mission. Twenty-seven miles beyond the Golden Gate, the craggy Farallon Islands have been home to fur-seal hunters from Russia, a gold-rush-era egg business, and even a nuclear waste dump. Today they’re home to 250,000 sea birds, not to mention seals, sea lions, whales, and sharks. What makes these stark-looking islands so attractive to wildlife?
